WINDOW-SASH.

SPECIFICATION forming part of Letters Patent No. 643,151, dated February 13, 1900.

Application iiledMay 19, i899. Serial No. 717,498. (No model.) l

To @ZZ whom it may concern:

Be it known that I, IsAAc N. OWENS, J r.,

a citizen of the United States, residing at Hannibal, in the count-y of Marion and State of Missouri, have invented a new and useful Vindow-Sashpf which the following is a specilication.

This invention relates to window sashes, and has for its object vto provide improved means for draining the moisture which may accumulate upon the inner sides of the window-glass.

To this end the present invention consists in the combination and arrangement of par ts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claim, it being understood that the improvement is susceptible of various changes in the form, proportion, size, and the minor details of construction Without departing from the spirit or sacrificing any of the advantages of this invention.

In the drawings, Figure 1 is a sectional perspective view of the meeting-rails of an upper and lower window-sash having the improvements applied thereto. Fig. 2 is a transverse sectional view thereof. Fig. 3 is a detail sectional'view taken longitudinally through the meeting-rail of the upper sash, showing the means for draining the moisture from the same.

Corresponding parts are designated by like reference characters in all the figures of the drawings.

Referring to the accompanying drawings, l and 2 designate, respectively, the meetingrails of the upper and lower sashes, and 3 the window-frame inclosing the sashes, and upon which the latter are slidably mounted in the common or ordinary manner. The upper inner edge of the upper meeting-rail 1 is out away, as shown, so as to provide an inwardlyprojecting shoulder 4, extending entirely across the length of the rail, and the upper face of said shoulder is grooved, as at 5, for the entire length thereof. The adjacent face of the meeting-rail 2 is provided with a 1ongitudinal shoulder 6, extending a suitable distance of the Vertical thickness of the rail and having its lower face conveXed, as shown, and

adapted to lit snugly within the complementary groove 5 of the meeting-rail 1, thereby interlocking the sashes together and preventing movement and consequent rattling of the same. By reason of this interlocking connection it will be seen that an angular or broken joint is provided which is adapted to exclude wind, dust, rain, duc., as will be readily understood. In View of the fact that the 6o upper and lower portions of the adjacent faces of the meetingrails are straight the sashes readily come together when closed Without binding, and the joint or interloclc ing connection may be as readily separated When either sash is being opened.

To drain the window-glass from moisture which may collect thereon, the upper face of the meeting-rail of the upper sash is provided with an open longitudinal groove 7 extending 7o the entire length of the rail and gradually increasing in depth from the center thereof outwardly in opposite directions. The opposite side rails 8 of the upper sash are each provided with a transverse slot 9, communieating longitudinally with the respective opposite ends of the groove '7, and the outer edges of the side rails are each provided with a vertical groove lO, communicating with the outer end of the slot 9 and openingoutthrough 8o the bottom of the rail. By reason of this construction it will be understood that any moisture collecting upon the glass 11 of the sash and running down thereupon will be received within the groove 7, and in view ofthe inclination thereof the moisture will be conveyed through one of the transverse slots 9 and the groove l0 to the upright stile vor side of the window-frame and thence to the window-sill, whereby the meeting-rail will be effectively 9o drained from all moisture, and thereby be preserved and protected from rotting. It will be understood that the lower sash may be provided with similar means for draining moisture therefrom.

The present invention provides a simple and improved construction in window-sashes in which the joint between said rails, and furthermore the window-panes, are effectually drained of all moisture, so as to protect the roo frame of the sashes against being rotted thereby.

outer ends of the transverse slots, and having their lower ends opening downward through the lower ends of the respective rails, sub- I 5 stantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto aliixed my signature in the presence of two witnesses.
